Information regarding M.A.C.E is currently still classified. Mostly because M.A.C.E. herself is still trying to figure out what her personality should be. She'll figure it out sooner or later. In the meantime she prefers to keep a low profile and observe.
Deathbringer, on the other hand, tends to be more outgoing despite being told a few times she should keep a low profile. This usually results in her just flying really close to the ground. She means well but high intelligence doesn't seem to be something she has. Kindhearted and curious, she sees everything as a new game and adventure. Despite being made of bubblegum, she seems to magically be able to avoid getting stuck to things. Such is the way of magical bubblegum bunnies.
